ColdFusion Tag of the Week: CFSAVECONTENT

Fri, 04 May 2007 08:46:18 GMT

Inspired by a recent post over at <cfsilence> and a handout Dave gave us at the last DFWCFUG meeting I decided I wanted to start a blog series. With this series of posts I hope to highlight a ColdFusion tag or function that people may have forgotten about or may not ever use. Or I may even highlight a tag that a lot of people use and that more should be aware of, <cfqueryparam> comes to mind. I will also use these posts to highlight codeShare, a project that Fro and I worked on and that Dave and Aaron did a great job integrating into InstantSpot . If you ever need to share code with someone over the Internet codeShare is a perfect place to do it. If you have any suggestions for a tag to highlight shoot me an email at ryan DOT Everhart AT gmail DOT com.

This may or may not get as loyal of following as Andy Jarrett’s Friday Jokes, but it’s worth a shot! So with out further delay the first every ColdFusion Tag of the Week!

This week’s tag is a tag that I’ve been using a lot of lately when writing AJAX with Rob Gonda’s ajaxCFC.

The Tag:
<cfsavecontent>

The Definition:
Saves the generated content of the cfsavecontent tag, including the results of evaluating expressions and executing custom tags, in the specified variable.

The Tag Sample:
[codeShare may1a619]

The Real Life Example:
[codeShare maye272b]

The Uses:
Like I mentioned above I use this a lot when working with AJAX. It allows me to write HTML code and send it back to the user thru javascript as a string. This is MUCH easier than trying to write HTML code using javascript. Another use for it may be to create content for use in a <cfmail>. There are some situations where you may need to output more than one query within a <cfmail> tag and its not always possible. However with <cfsaveconent> it is possible, in fact your <cfmail> tag may even look a bit cleaner if you use <cfsaveconent>

The Bonus Code:
[codeShare mayb4916]

Good Day!

I’ve been called a lot of mean things in my life some to my face and surely more behind my back. However the other day I got called a name by a guy I don’t even know! This guy, Todd, if that is his real name, called me a lurker!!! A lurker??!! How can you call me a lurker if you don’t even know me Todd??

Well Todd didn’t just call me a lurker he called A LOT of ColdFusion developers lurkers or takers. We can define lurkers or takers in this case as developers that take code from blogs or other community sites but don’t give back to the community. For whatever reason, either they are too busy or too lazy they just don’t give back. Therefor Todd proposed a challenge. The challenge was for us all to get more involved in the ColdFusion Community, write a blog, join a CFUG or mailing list. Do something to give back.

Well Todd, challenge accepted! I’m going to try my best to make time to give back. What I say here on my InstantSpot may seem silly to those more experienced than I, so for that I apologize and welcome all feedback.

If you are new to the ColdFusion or Blog thing, here are some of the hot spots I visit often,.
